LaTeX is easy and straight forward ! a simple document using Latex is shown below:

\documentclass[a4paper,11pt,twocolumn]{article} \usepackage{amsmath,times} \usepackage{graphicx} \usepackage{tabularx} \begin{document} \title{The title of your article here....} \author{I. Bouchrika and A. Another \\ University of ABC \\ address here of your university \\ Country, post code} \date{} \maketitle \begin{abstract} This is the text for my abstract ..... \end{abstract} \section{introduction} text for the introduction \textit{here} text for \textbf{the }introduction \underline{here} text for the introduction here \end{document}

\textit{text} ITALIC TEXT

\textbf{text} BOLD TEXT

\underline{text} Underlined text

For inserting Equation within a text, we use $ equation here $as shown in the example :

\section{introduction} the introduction here as shown for $x=f(t)$ text for the introduction here text for the introduction here

If you want to insert equation on its own, we use the \begin{equation} and \end{equation}:

\section{introduction} the introduction here as (\ref{eq:myeqa}) text for the introduction here text for the introduction here \begin{equation} x=\sum{f(t))} \label{eq:myeqa} \end{equation}

Note that the equation block has the command \label{eq:anythinghere}. This is a label or an address that we can within the text to refer to the equation using the command \ref{eq:anythinghere}

To insert an image or a figure, we need first to import the package graphicx using the command : \usepackage{graphicx}. We use the command \begin{figure} and \end{figure} as shown below:

\section{introduction} the introduction here as (\ref{fg:myfig}) text for the in.... \begin{figure}[h] \centering \includegraphics[width=3cm]{nameofyourimage.jpg} \label{fg:myfig} \caption{Title of your image here} \end{figure}

The output of the above is :

The option [h] inside \begin{figure}[h], means place the picture HERE.

Tthe command \centering is to align the image into the middle (center ).

The main command is \includegraphics[options]{pathofyourimage.jpg] Options can be : width, height, angle

The \caption command is for the title of the text.
